NAME
clog(), clogf(), clogl(), clogw(), clogq() - complex natural (base-e) logarithm functions SYNOPSIS
DESCRIPTION
returns the complex natural logarithm of z in the range of a strip mathematically unbounded along the real axis and in the interval [-iPi,+iPi] along the imaginary axis. There is a branch cut along the negative real axis. is a version of it takes a argument and returns a result. is a version of it takes a argument and returns a result. is an version of it takes an argument and returns an result. is equivalent to on HP-UX systems. USAGE
To use these functions, compile with the default option. To use compile with the option. Make sure your program includes Link in the math library by specifying on the compiler or linker command line. RETURN VALUE
= returns -Inf+iPi and raises the divide-by-zero floating-point exception. returns -Inf+i0 and raises the divide-by-zero floating-point exception. returns +Inf+iPi/2, for finite x. returns NaN+iNaN and optionally raises the invalid floating-point exception, for finite x. returns +Inf+iPi, for finite positive-signed y. returns +Inf+i0, for finite positive-signed y. returns +Inf+i3Pi/4. returns +Inf+iPi/4. returns +Inf+iNaN. returns NaN+iNaN and optionally raises the invalid floating-point exception, for finite y. returns +Inf+iNaN. returns NaN+iNaN. ERRORS
